2,2,2-三氟苯乙酮是合成 f 3-三氟甲基-3-苯基双吖丙啶的起始物料 。用光学活性格氏试剂进行不对称还原，形成 2,2,2-三氟-1-苯乙醇 。它与联苯、三联苯（联苯与三联苯、苯基醚和二苯氧基二苯甲酮的混合物）发生缩合反应，形成新的芳香族 3F 聚合物。 用途 2,2,2-三氟苯乙酮用于合成新型含氟聚合物，具有较高的平均分子量、较高的热稳定性和良好的成膜属性。 Product Introduction 2,2,2-Trifluoroacetophenone is the starting material for the synthesis of f 3-trifluoromethyl-3-phenyldiazirine. It undergoes asymmetric reduction with optically active Grignard reagent to form 2,2,2-trifluoro-1-phenylethanol. It undergoes condensation with biphenyl, terphenyl, a mixture of biphenyl with terphenyl, phenyl ether and diphenoxybenzophenone to form new aromatic 3F polymers. Application 2,2,2-Trifluoroacetophenone was used in the synthesis of new fluorinated polymers, having high average molecular weight, high thermal stability and good film-forming properties.
